Outsourcing Software Development to Korea
When outsourcing to South Korea makes sense, engagement models, Korean contract norms, time zones and vendor checks, from a two-person studio in Korea.
Outsourcing software development to South Korea makes sense when the product has to work for Korean users: Korean payment gateways, KakaoTalk notifications, Naver search, Korean-language admin screens and a privacy notice written for Korean law. It makes less sense if the only goal is the lowest hourly rate. This guide covers engagement models, how Korean contracts are usually structured, time zones, and how to vet a vendor. It is written by NQ Solution, a two-person development studio in Korea, so the last section is about what hiring a team our size actually means.
When does outsourcing to South Korea make sense?
Most companies that look for a developer in Korea are not shopping for cheap capacity. They need something that works properly inside the Korean market, and that is easier when the people building it read the Korean documentation, contracts and review processes first-hand.
Good reasons to build in Korea:
- Your users are in Korea. Card payments usually go through a Korean payment gateway, customers expect KakaoTalk messages rather than SMS or email, and Naver still matters for search. Our guides to Korean payment gateways, KakaoTalk Channel and AlimTalk and Naver SEO go into each one.
- You need Korean and English to work together. A bilingual site is more than a translated copy: it needs separate URLs, hreflang tags and an admin that both language teams can edit. We built the Korean–English technical site for EMECS and the Korean–English site for UNESCO i-WSSM, which is live.
- Your Korean partner or subsidiary signs the contract. A Korean vendor can contract in Korean, issue Korean tax invoices and work with your Korean staff directly.
- The work is a defined product, not a headcount. A web app, an internal system or a website with a clear feature list fits a fixed-scope project well.
Less good reasons: you need a large team on call around the clock, the work has no Korean element at all, or the brief is "the cheapest possible". Korea is not a low-cost offshore market, and a small studio is not a staffing agency.
Which engagement models are common?
Korean vendors use the same broad models you will see elsewhere. What changes is how much of the risk each side carries.
| Model | How the price is set | Works best for | Watch out for |
|---|---|---|---|
| Fixed scope | A quote per feature, paid in instalments | A product with a clear feature list | Anything not in the feature list is a change request |
| Time and materials | Hours or person-days, billed monthly | Research, unclear scope, long-running work | Budget control sits with you |
| Dedicated team | Monthly fee per developer | Large products needing several full-time people | Needs a vendor with enough staff to swap people in |
| Maintenance retainer | Monthly or yearly fee | Running a product after launch | What counts as maintenance versus new work |
We work on fixed-scope projects. We quote by the features you need rather than by page count, the quote items become the contract scope, and payment is split into instalments tied to checkpoints. Hosting and maintenance after launch are a separate contract.
How are software contracts usually structured in Korea?
There is a legal baseline. Korea's Software Promotion Act requires software project contracts to be made fairly, and it voids contract terms that are "remarkably unfair", such as refusing without good cause to adjust the price or deadline when the scope changes (Article 38). The same article has the Ministry of Science and ICT prepare a standard contract for software projects and recommend its use. Many Korean contracts borrow their clause order from it.
For projects with State agencies, the Act also sets a one-year defect warranty from the project's completion date (Article 60). Private contracts set their own period, so read that clause rather than assuming a default.
A few habits you will see in almost every Korean quote and contract:
- Prices exclude VAT. Quotes are normally written "부가세 별도" (VAT excluded). Korea's standard VAT rate is 10%. How VAT applies to a client outside Korea is a question for your accountant.
- Payment comes in instalments. A deposit at signing, sometimes an interim payment, and the balance at acceptance.
- Changes are made in writing. A scope change should come with its own estimate and schedule impact before work starts.
Here is what to ask about each clause, and how we handle it in our own contracts:
| Clause | What to ask | How NQ Solution handles it |
|---|---|---|
| Scope | Is the feature list attached to the contract? | The quote items become the contract scope |
| Payment | What do I check before each instalment? | 70/30, 40/30/30 or 40/20/20/20 depending on size, each tied to a checkpoint such as an interim build or final acceptance |
| Acceptance | How long is the acceptance period, and what counts as a pass? | Written into the contract |
| Defect warranty | How long, and how are defects separated from new requests? | The warranty period is written into the contract; maintenance is a separate contract |
| Source code and IP | When is the source handed over, and who owns new code versus the vendor's existing libraries? | The handover terms for the source code and other deliverables are written into the contract |
| Hosting and maintenance | How does it renew, and how do I leave? | A separate contract; its billing cycle and renewal terms are written into it |
| Governing law | Which country's law applies? | Stated in the contract; raise it before the quote is final |
If you need the contract in English, or under another jurisdiction, raise it before the quote is final. It is much harder to change once the rest of the terms are agreed. If the terms matter to your business, have a lawyer review them; this article is general information, not legal advice.
How do time zones and communication work?
Korea Standard Time is UTC+9 all year, with no daylight saving. That makes the overlap predictable:
| Your office | When it is 09:00 in Seoul | When it is 17:00 in Seoul |
|---|---|---|
| London | 00:00 (winter) / 01:00 (summer) | 08:00 (winter) / 09:00 (summer) |
| New York | 19:00 / 20:00 the previous day | 03:00 / 04:00 |
| San Francisco | 16:00 / 17:00 the previous day | 00:00 / 01:00 |
| Singapore | 08:00 | 16:00 |
| Sydney | 10:00 (winter) / 11:00 (summer) | 18:00 / 19:00 |
In practice: Europe overlaps with the Korean late afternoon, the US west coast with the Korean morning, and Southeast Asia and Australia with most of the day. Projects across the bigger gaps run on written updates rather than daily calls. Write requirements down, keep one shared record of decisions, and expect answers the next working day rather than the same hour.
For Korean clients we keep the quote, contract, schedule, files and maintenance requests in one client portal. The portal's sign-in codes are sent by text to Korean mobile numbers, so when a client has no Korean number we run the project by email instead.
Paying from abroad is straightforward: we can bill in USD or by overseas transfer, and when it helps, we meet in person in Korea for kick-off or acceptance.
Two calendar notes. Seollal (Lunar New Year) and Chuseok (the autumn harvest festival) are multi-day national holidays, so do not plan a launch on either. And if you have heard of Korea's "52-hour rule", that is the cap on the working week under the Labor Standards Act. It applies to Korean employees, which matters if you hire staff in Korea rather than contract a company.
How do you evaluate a Korean development vendor?
Directories such as Clutch, GoodFirms and The Manifest dominate the search results for Korean development companies, and their verified client reviews are a reasonable place to start. Some good small studios are not listed, though. We are not on these directories yet as of October 2026, so here is the checklist we would use ourselves:
| Check | How to verify it |
|---|---|
| Live work, not mock-ups | Open the sites. Switch languages. Check that the admin claims match what you can see |
| Who actually builds it | Ask for the names and roles of the people who will write the code, not only the salesperson |
| A registered business | A Korean company has a 10-digit business registration number, and you can check that it is active on the National Tax Service's Hometax site. Ours is 867-36-01532 |
| A quote broken down by feature | A single lump sum makes change requests impossible to price fairly |
| A sample contract before you commit | Read the payment, acceptance, warranty and source code clauses first |
| Korean integration experience | Ask what they have shipped, not what they can do. "We can" and "we have" are different answers |
| How they handle questions | Send a one-page brief. A vendor who asks good questions about it is worth more than one who replies with a price within the hour |
What does hiring a two-person studio mean?
NQ Solution was founded in 2024. Our CEO and a director design and build every project themselves. There is no account manager between you and the code, and the person you explain a requirement to is the person who implements it.
The trade-offs are real, and you should weigh them:
- Capacity is limited. To keep the work at the standard we want, we limit how much we take on at once, depending on scope. If our schedule is full, we tell you the next possible start date during the consultation.
- There is key-person risk. With two people, the honest answer is a contract that makes the work portable: the handover terms for the source code and deliverables are written in, so another team can pick it up.
- We are not a staffing agency. If you need five full-time developers for a year, a larger firm is the better fit.
What you get in exchange: one consistent pair of builders from the first call to the release. We mostly work in Next.js and TypeScript, and use Spring Boot or Python when a project calls for it. Many clients come back for a second phase after the first build. You can see the work on our portfolio, and what we build is described on the software development in Korea and web development in Korea pages.
How much does it cost to build software with us?
These are the ranges from our pricing catalogue (version 1.1, dated 23 September 2026). They are supply prices in Korean won, excluding VAT:
| Project type | Range (KRW, excl. VAT) | Typical duration |
|---|---|---|
| Website, three tiers | 2.6M / 4.4M / 6.0M | Agreed in the quote |
| Web app (sign-up, database design, one or two core flows, admin) | 2.5M–5.5M | 6–12 weeks |
| Internal business system (ERP-style) | 2.0M–6.0M | 4–10 weeks |
The 2.6M website tier is a simple CMS build; the higher tiers add more. Third-party costs such as payment gateway fees, message sending fees and AI API usage are passed through at cost and listed separately in the quote. For a detailed breakdown of internal system costs, see custom ERP development cost in Korea. The estimate calculator gives you a range for your own feature list.
Frequently asked questions
How much does it cost to outsource software development to South Korea?
It depends on scope more than on location. In our pricing catalogue (version 1.1, 23 September 2026), a web app is KRW 2.5M–5.5M and an internal business system KRW 2.0M–6.0M, excluding VAT. Compare vendors on the same feature list, not on hourly rates.
Is outsourcing to South Korea expensive?
Korea is not a low-cost offshore market, so if price is the only criterion there are cheaper options. Building in Korea pays off when the product needs Korean payments, KakaoTalk, Naver or Korean-language operations, because that work is done by people who deal with it every day.
What is the 52-hour rule in South Korea?
It is the weekly working-time cap under the Labor Standards Act: 40 regular hours plus up to 12 hours of extended work, with a week counted as seven days including holidays. It governs Korean employees. When you contract a company, the company manages its own staff's hours.
Can I work with a Korean developer in English?
Yes. Our English-speaking founder handles English consultations, meetings and documents directly, without an interpreter. You can send requirements through our English request form and run the project by email. Ask any vendor early which language the contract will be written in, and which version prevails if there are two.
Who owns the source code when you outsource to a Korean company?
The contract decides it, so read the intellectual property and source code clauses before signing. Check when the source is handed over and how the vendor's existing libraries are licensed to you. In our contracts, the handover terms for the source code and other deliverables are written in before work starts.
